7Z11Z- Method for preparation of 7Z11Z-Hexadecadienal as major sex pheromone of citrus leafminer Phyllocnistis citrella

摘要

The present invention relates to a manufacturing method of a sex pheromone of a citrus leaf miner (phyllocnistis citrella) for controlling the citrus leaf miner. More specifically, the present invention relates to a method for manufacturing (7Z, 11Z)-hexadecadienal which is a main component of the sex pheromone of the citrus leaf miner from a cheap starting material with high purity and yield while being efficient, simple and economical. The manufacturing method of (7Z, 11Z)-hexadecadienal displayed by chemical formula 1 comprises a step of manufacturing a compound displayed by chemical formula 3 by making an aldehyde compound displayed by chemical formula 2 react with n-pentyl triphenylphosphonium halide through a Wittig reaction, and performing an oxidation reaction.
